Los Angeles -LRB- CNN -RRB- -- Brooke Mueller has reconsidered her decision to undergo at-home drug rehab . Instead , Charlie Sheen 's ex-wife has checked into an in-patient treatment center , her spokesman said Tuesday .

Mueller was arrested in Aspen , Colorado , on December 3 and charged with assault and cocaine possession , police said .

Mueller 's publicist told CNN Monday that she would `` take a different approach to deal with her addiction '' with a daytime rehab program and around-the-clock supervision at home .

`` After further reflection and consideration , Brooke has decided to remove herself from the media spotlight and has entered a long-term in-patient treatment center where she can focus on her recovery without distraction , '' spokesman Steve Honig said Tuesday .

Mueller , 34 , checked into the rehab facility before the announcement was made , he said .

`` Brooke 's goal is to maintain her sobriety and she believes this is the best option to reach that goal , '' Honig said .

The 2-year-old twin sons she shares with Sheen `` will remain in their home and familiar surroundings and be under the care of their longtime nanny , '' he said .

`` Charlie and Brooke 's parents fully support her decision and everyone recognizes the importance of maintaining the children 's normal routine , '' he said .

The incidents in Aspen began when a woman at the Belly Up -- a bar and performance venue there -- complained that Mueller had been `` the aggressor '' in an assault , Aspen police said .

Mueller was found and arrested after midnight at another bar , Escobar , police said . She was charged with possession of cocaine with intent to distribute , which is a felony , and third-degree assault , which is a misdemeanor .

She was released after posting an $ 11,000 bond , Aspen police said . A court date is scheduled for Monday .

Mueller has appeared as an actress in several movies , including 2004 's `` A Love Song for Bobby Long , '' according to IMDb . But she is more widely known as the ex-wife of Sheen .

The twin sons and Mueller were part of Sheen 's volatile public fall-out with CBS earlier this year as he left his starring role on the network 's `` Two and Half Men . ''

She claimed in March that he 'd threatened to kill her , saying , `` I will cut your head off , put it in a box and send it to your mom , '' according to a declaration made in a restraining order against Sheen . The revelations led to a court order removing the 2-year-old boys from Sheen 's home .

The actor called the allegation `` colorful '' and described the quote attributed to him as fabricated in an interview with NBC 's `` Today Show . ''

Mueller has sought help for substance abuse and stress-related issues in the past .

Last December , her attorney , Yale Galanter , said that she entered a sober living facility . Earlier , in April 2010 , Mueller had checked into a treatment facility for help with stress management to prevent a `` return to old problems , '' her representative said .

She was in substance abuse rehab earlier in 2010 `` to get her health in order , '' Galanter said at the time .

The couple was involved in an alleged domestic dispute in Aspen on Christmas Day 2009 that resulted in felony charges against Sheen .
